Sensitivity, specificity, positive- and negative-predictive values of TUI to detect congenital heart disease.

	# of patients available for analysis	Prevalence	Sensitivity	Specificity	Positive predictive value	Negative predictive value
B-mode imaging	115^†	12.2% (14/115)	85.7% (12/14)	100.0% (101/101)	100.0% (12/12)	98.0% (101/103)
Color Doppler	98^‡	14.3% (14/98)	92.9% (13/14)	98.8% (83/84)	92.9% (13/14)	98.8% (83/84)

^†

Complete follow-up was available in 131/172 patients scanned by B-mode imaging (76.2%) (excluding cases of isolated VSDs). Sixteen patients were excluded from this portion of the analysis: one patient whose images were interpreted as tetralogy of Fallot but who was found at the time of surgery to have a subaortic VSD associated with transposition of the great arteries, and 15 patients whose ultrasonographic images were considered to be of poor diagnostic quality.

^‡

Complete follow-up was available in 105/142 patients scanned by color Doppler (61.0%) (excluding cases of isolated VSDs). Seven patients were excluded from this portion of the analysis: in all cases, the ultrasonographic images were considered to be of poor diagnostic quality.

TUI: Tomographic Ultrasound Imaging; VSF: ventricular septal defects.
